Why is genetic variation important for the long term survival of a population?
Explanation:
According to Darwinism , the survival of the fittest , variation is important because it allows species to adapt to its environment , the stronger in traits is selected and the weakest is unable to adapt and die.
so , variation is the only way for a species to acquire new traits that can enable them to survive and adapt to their surroundings, Normally , Variation is very slow and it requires many generations for new traits to emerge , but it happens.

A student proposes that left-handedness is a recessive trait and is hidden in much of the human population. a survey of his class of 36 students finds that 9 students are left-handed. using the hardy-weinberg formula, what would be the expected allelic and genotypic frequencies in this theoretical population
The frequency of the recessive allele for the left handle will be in this case equal to q^2 = 0.25 >> q = 0.5.
What is the Hardy Weinberg principle?The Hardy Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies.
The Hardy Weinberg principle states that the sum of the dominant allele and the recessive allele in a population is equal to 1 (p + q = 1).
This principle also states p2 + q2 + 2pq = 1, where p^2 is the dominant homo-zygous allele, 2pq the heterozygous frequency and q^2 the recessive homo-zygous frequency.
In this case, 9 individuals represent 25% (q^2 = 0.25), thereby the feecuency of q is equal to √0.25 = 0.5.

Mira analyzed oxygen and carbon dioxide in inhaled and exhaled air. she found that the percentages of both gases were different in each. what other gas would most likely also have different amounts in inhaled and exhaled air? ozone (o3) hydrogen (h2) water vapor (h2o) sulfur dioxide (so2)
The amount of different gases varies in environment. Just like oxygen and carbon dioxide, Water vapor also have different amounts in inhaled and exhaled air.
What is breathing?Breathing is the process of inhaling oxygen and removing carbon dioxide.
During breathing amount of inhaled air contains 21% of oxygen and 0.04% of carbon dioxide,while during exhalation 16.4% of oxygen and 4.4% of carbon dioxide is there.
The reason behind such variation is that cells use oxygen from the inhaled air to release energy and give out carbon dioxide as a byproduct.
Water vapor is also inhaled and exhaled in different amounts just like oxygen and carbon dioxide.
Thus, the correct option is C.
